550 on it now. it's starting to get a little better. still rattles more than i would like it to on no-throttle deceleration in the 2-3k range and it's still quite touchy in 1st with choppy/chatter, nearly stall, or pull your face off grip. Worse, it's inconsistent and any of those 3 may happen at any time. Hoping it clears up a bit more
